Kinda fascinated by the variety of responses --- very open to hearing people telling me we need to chill out, because we are first timers and that may well be the case. On the other hand, we're quite easygoing about a lot of other things --- ie what he eats etc., wears and even sunscreen --- fwiw we usually don't bother with it at all but when he's going to the pool or beach we feel like he should be wearing it. Was just kinda shocked to have someone try to argue with us on a few issues that are important to us.
I think more than any one of the single issues you've brought up is the dismissive attitude that's a problem. If your FIL doesn't respect that you call the shots when it comes to your kid, then that's just not a winning situation, IME. Some things are simply not up for discussion and if your FIL wants to argue about it with you in front of your kids, obviously that's not going to work.
I'd have your husband say something in whatever format works for his family, whether it's a "Dad, cut it out" in the moment to nip it in the bud, or a sit down conversation "there's something that we need to resolve" and if he's not willing to do that, or if your ILs are completely hostile to the message, then I'd thank them for their kind offer, but that just point out the obvious - that you owe daycare full tuition regardless of whether you use it 80% or 100% of the time, so you'll end up enrolling Junior in full time care, and if they're open to it, take the ILs up on their offer when you need back-up care, or date night sitting, and then only actually utilize that option on terms that you feel comfortable with.
